In the key link of deep mine mining and vertical material transportation, facing the severe challenge of high tension, strong impact and complex working conditions, the reliability of the sidewall conveyor belt of the mine vertical lifting system is put forward to be almost demanding.

     QBF rubber is deeply rooted in its relentless pursuit of “R&D capabilities” and “process control,” establishing a comprehensive support system covering on-site installation and professional maintenance. It has become the preferred partner for numerous large-scale mining enterprises both domestically and internationally. Currently, QBF rubber holds two industry records in the mining sector: the longest single one sidewall conveyor belt (930m – Mexico Silver Mine Project) and the highest vertical lift for a sidewall conveyor belt (255m – China Gold Mine Project).
